Title: Method and apparatus for treating water, double electrode fixed bed type electrode electrolytic cell, and method for installing grounding electrode
Inventor: MURAKAMI TAKASHI
IPC: C25B9/17
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To improve the blockade of electrodes by foreign matters, etc., and to make durability improve by forming water-introducing and water-discharging water passage ports of raw water in an electrolytic cell and enabling raw water passing through the cell to pass in the reverse direction when raw water is passed through double electrode fixed bed type electrodes to be treated electrochemically. SOLUTION: Raw water sent from a water storage tank 100 is divided, passes through three-way cocks V3, V4, is introduced from the A side of an electrolytic cell EC, is discharged from the B side, passes through the cock V4, and is led to a water discharge system. On this occasion, cocks V3, V4 are changed over, the raw water in the cell EC is made to pass through the cock V4, to be introduced from the B side of the cell EC, to be discharged from the A side, to pass through the cock V3, and is led to the water discharge system. By changing over the cocks V3, V4 and inverting the water passage direction in the cell EC, clogging in the cell, especially on the most upstream side, is reduced remarkably. The periodic inversion of the water passage direction is effective to prevent clogging.

Title: Name printer for medical x-ray film
Inventor: ETO KIMIHIDE
IPC: A61B6/00
Filed: 1990-10-26
Abstract: PURPOSE:To record a reversed name in white and black in an X-ray film by making a light image into a reversed image in white and black for the read-out name. CONSTITUTION:A name card reader 1 reads out a name card, and a memory 2 stores it according to the indication of an address generator 8. Next, the stored name card is read out from the memory 2 according to the indication of the generator 8. At this time, the data are reversed by an inverter 9. Since the name data of the memory 2 are memorized in a form of white and black, it is changed into reversed data in white and black by making it pass through the inverter 9. The reversed name data are converted into an analog signal with a DA converter 3, and a name picture image reversed in white and black on a CRT4 is displayed. The picture image is formed by an image-formation lens 5 and is reflected by the mirror 6 to be radiated on the X-ray film 7. Accordingly the reversed name picture image in white and black is recorded on the film 7.

Title: Supervisory controller for power system
Inventor: NAGAMATSU MICHIE
IPC: G05B9/03
Filed: 1991-10-09
Abstract: PURPOSE:To minimize missing of supervisory control by making an automatic switch to other lightly failed TC master station upon failure of one master station (TC master station). CONSTITUTION:Upon failure of a TC master station, a TC master station monitoring means 213 receives TC master station failure information through a transmitting means 211 or 212 and thus received information is stored in a TC master station failure information area 218. A switching decision means 214 compares the failure state between TC master stations A31 and B32 with reference to the TC master station failure information area 218 and requests a switching means 215 to make a switching to a lightly failed TC master station. The switching means 215 then exchanges the mode areas 216 and 217 for every line and switches the TC master station. Consequently, switching can be made automatically to a lightly failed TC master station upon failure of the TC master station. According to the invention, supervisory control of power system is prevented from being disabled due to erroneous manual switching and missing of supervisory control information can be minimized.

IPC: H01J61/16
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp having small leak current. SOLUTION: A discharge lamp 1 has a luminescent tube 2 as a straight tube shaped inner tube and is provided with cool cathode 3, 3 via a lead wire 3a on both ends of this luminescent tube 2. Around the luminescent tube 2, an outer tube 5 surrounding the luminescent tube 2 is provided via a clearance 4 of a vacuum pressure of substantially 10<-5> Torr. A gas absorption better member 6 is housed in the clearance 4. A voltage is applied between cool cathodes 3 and 3 by a lightning circuit 7, and the lamp is started and lit. Mercury vapor is excited by discharge between cool cathodes 3 and 3, a ultra-violet ray of 147nm and 254nm in wavelength is excited, and a three-wave length phosphor is light-emitted.  Since a clearance 4 is substabtuyally vacuum of 10<-5> Torr, a floating capacity decreases, discharge from the luminescent tube 2 to a proximal conductor becomes small, a leak current can be lowered, a triggering voltage can be lowered, and a lighting maintenance current can be reduced.

Title: Semiconductor pressure sensor
Inventor: KAWAHIRA TETSUYA
IPC: H01L29/84
Filed: 1992-10-29
Abstract: PURPOSE:To use a gauge pressure sensor under usage environment where a sudden high pressure is generated by providing a mechanism for closing down the atmospheric opening of a semiconductor pressure sensor when the pressure at the atmospheric opening side of the semiconductor chip exceeds a specific pressure. CONSTITUTION:The open edge on the lower side of a leakage-prevention valve 30 is fixed to a sate pressure semiconductor pressure sensor so that an upper hole 22a of a package 22 is covered. When a high pressure is suddenly fed to the sensor and the pressure of a medium to be measured exceeds a specific pressure, a semiconductor chip 18 is damaged due to the crack, etc., of a diaphragm, the medium to be measured leaks into the package 22 and then jets into the valve 30 via the hole 22a. The high-pressure medium to be measured allows a ball 34 to be pushed out and to be engaged to the inner wall of the upper side (taper part) of the valve 30 against the elastic force of a spring 36. Therefore, an atmospheric opening hole 32a is closed, thus preventing the medium to be measured from being leaked to the outside of the sensor and hence performing measurement from a low to high pressure according to gauge pressure as desired.

Filed: 1992-10-29
Abstract: PURPOSE:To prevent the interference of an upper cap and a head supporting arm and to reduce the size over the entire part of the device by luffing the upper cap and the head supporting arm in always the specified state of the spacing between the upper cap and the head supporting arm. CONSTITUTION:The axial center line L1 of a pivotal shaft 23 which is the luffing center of the upper cap 22 and the axial center line L2 of a supporting shaft 14 which is the luffing center of the head supporting arm 13 are set on the same axial center line, and therefore, the upper cap 22 and the head supporting arm 13 are integrally luffed around the one axial center line by the same rotating angle. Then, always the specified spacing is maintained without generating a relative change between the upper cap 22 and the head supporting arm 13. The head supporting arm 13 luffs integrally with the upper cap 22 in this state, and therefore, the front end of the head supporting arm 13 does not interfere with the upper cap 22. There is, thereupon, no need for assuring more than the necessary clearance between both and the size over the entire part of the device is reduced.

Filed: 1986-12-08
Abstract: PURPOSE:To execute amplification/detection of excellent linearity by generating a gain control signal corresponding to the detection output level of a double balanced differential amplifier, and varying the proportion between currents that flow through two current sources. CONSTITUTION:From the relations in potential between the bases and the emitters of transistors (TR)Q5-Q8, an formula I is established, assuming that current I1=I2=Ii; I3=2I0, the amplification ratio and the saturation current of TR are respectively (h) and Is; signal current flowing through a resistor R5 is is; and currents flowing through the respective collectors of TR Q7, Q8 are I7 and i8. From this formula, i7=(I0/Ii)(Ii-is) and is=(I0/Ii)(I0+is) are established, and further, a detection output V0 is proportionate to the output V0' of an amplifier in case TR Q9-Q12 are absent, resulting in that V0'=RL(I0/Ii)2is assuming V0'=R7is-R6i7 and 6=R7=RL. In the case of beat detection, an equation II is established where omegap and omegas are the angular frequencies of video and voice carrier waves respectively, and (a) shows the maximum amplitude. An output following the bear detection is expressed by an equation III. Accordingly, the output gain can be controlled by varying the (I0/Ii).
